Charging system problem!!!!

[dauna50]

I own a 1999, 1.6L Mazda Protege, the battery is always discharging. I paid a lot, the battery has been changed, the alternator is new (3 rd one!), the CPM has been replaced by a new one. I checked the voltage output & I get again 12-12.5 volts! What's wrong in the mechanix diagnostic? Could somebody help me? Where can I find charging system diagram on the web?

Does somebody meet the same problem?

Thanks, best regards.

This sounds like a problem my dad had with his car. He replaced the battery, replaced the alternator, and the battery still kept dying on him every couple days. Turns out the switch that controls that little bitty light in the trunk that turns on when it opens was broken, so the light wasn't turning off, and it was draining the battery. I'd be willing to bet you have something(maybe your trunk light, maybe something else) that is staying turned on 24-7 and is draining your battery.
